ppl'ication filed July `6, 1910. Serial No. 570,644.

To all whom it may concer/n:

Be it known that I, MOSES WV. HARVEY, a citizen of the United States,residing at Foresthill, in the county of Summers and State of WestVirginia, have invented a new and useful Hoof-Plane, of which'thefollowing is a specilication.

It is the object of the present invention to provide an improvedconstruction of hoof plane. Ordinarily, a coarse rasp is employed inplaning or Smoothing down the hoof of an animal being shod but such implements are undesirable for the reason that they soon become cloggedand do not rapidly remove the material of the hoof.

It is therefore the object of the present invention to provide a hoofplane or rasping device which will overcome the disadvantages of theordinary rasp employed.

The device embodying the present invention consists, in part, of a platehaving a number of small cutting tongues, similar in form and functionto a plane bit, stamped up therefromg'and one feature of the inventionresides in the provision of means for flexing this plate so that thecutting edges of the said tongues may be caused to project to a greateror less distance from the working side of the plate.

With the above and other objects in view, the invention consists in thegeneral construction and arrangement of parts shown in the accompanyingdrawings, in which,

Figure 1 is a plan view of the hoof plane embodying the presentinvention. Fig. 2 is a side elevation thereof, the plane being shown inone condition in full lines and with its plate .flexed in dotted lines.Fig. 3 is a transverse sectional view through the plane looking towardone end thereof.' Fig. 4 is a plan view of a portion of the scraperplate of the plane illustrating a slight modificat-ion of the form ofthis plate. Fig. 5 is a detail longitudinalfsectional view through aportion of the scraper plate of the same. Fig. 6 is a detail perspectiveview of a tongue setting tool and wrench employed in connection with theplane.

In the drawings, the plane embodying the present invention includes, inits structure, a scraper plate which is indicated by the numeral 10 and,while of stout sheet metal possesses a certain degree of resiliency andflexibility which will result in its normally assuming a flat positionbut adapt it to be fleXed to various degrees of curvature. The

plate is formed with a number of openings 11 and at one side of eachopening the material yof the plate is struck down to alford a scrapingtongue 12 the projecting edge of which is sharpened to a cutting edge.In Fig. 1 of the drawings, these tongues are illustrated as arranged intransverse series one series behind another, the tongues of adjacentseries alternating.

Each end of the plate 10 is bent up substantially at right angles as at13 and is formed with an opening 14 and through these openings isinserted the shank 15 of a handle 16. At and adjacent its points ofengagement through the openings 14, the shank 15 of the handle 16 isthreaded as at 17 and upon each threaded portion of the shank are nuts18 adjustable to bear against opposite sides of the corresponding ends13 of the plate 10. From the foregoing description of this portion ofthe invention, it will be readily understood that by loosening the nutswhich bear against the opposed faces or sides of the ends 13 and thentightening the other nuts bearing against the outer faces of these saidends, compressed force may be brought to bear against the said ends ofthe plate thereby flexing or curving its body portion to a greater orless degree as shown in dotted lines in Fig. 2 of the drawings, the saidbody being thus curved in the direction of its length. When the body 10of the scraper plate is in normal or flat condition, illustrated in fulllines in the said Fig. 2 of the drawings, the cutting edges of thetongues 12 will project but a slight degree beneath the under side ofthe said body of the plate but when the body'of the plate is flexed asabove stated, these tongues will have their cutting edges projecting toa greaterkor less degree beneath the under side of the said plate,depending upon the degree of curvature to which the plate is flexed.Thus, if the plate is flexedV to a considerable degree the cutting edgesof the tongues 12 will project quite a distance beneath the under sideof the plate and will consequently cut: off larger portions of the hoofat each stroke of the plane. As here tofore stated, the tongues 12 arearranged in transverse series and in transverse alinement as shown inFig. 1 of the drawings but they may be arranged in staggered orirregular fashion as illustrated in Fig. 4 of the drawings.

The use of the tool illustrated in Fig. 6 of the drawings, as a wrench,will be readily understood and when it is to be used in setting tonguesl2 its end 19 is inserted in the opening related to the tongue to be setwith its inclined edge 20 seating against the tongue, and a blow is thenstruck upon the shoulder 2l, with a hammer or other suitable implement,to spring down the tongue.

That is claimed is:

l. A hootl plane comprising a scraper plate having upturned ends, and ahandle having a shank fitted through the ends and adjustable withrespect thereto, whereby to Iiex the plate to various degrees ofcurvature.

2. A hoof plane comprising a scraper plate having upturned ends, ahandle hav ing a shank engaged through openings in the said ends of theplate, the portions of the shank at and adjacent1 the point ofengagement through the openings being threaded, and nuts threaded uponthe said portions of the shank and bearing against the said upturnedends of the plate, the nuts being adjustable upon their respectivethreaded shank portions to exert pressure against the ends of the plateto flex the same to various degrees of curvature.

In testimony that I claim the foregoing as my own, I have hereto aliixedmy signature in the presence of two witnesses.
